ROLLING FLANGED METAL BEAM OR- BAR.

Original No. 1,034,361, dated July so, 1912, Serial no. 199,630, filed March 23, i904. Application for reissue filed. April 18. 1925. Serial No. 24,286.

T 0 all whom. it may; (owner/1,:

Be it known that llnxnv GREY, deceased, late a resident oi New -York city, in the county of New York and State of New York, (lid invent certain new Improvenicnts in Rolling Flanged Metal Beams or Bars, for which Letters Patent No. 1,034,361 were granted to him under date of July 30, 1912, which said Letters Patent were duly assigned to the American llnivcrsal Mill Company, a corporation of the Flute of South Dakota, and having its principal place of business at Scranton. in the county of Lackawanna and State of l-ennsylvunla, and that said corporation now makes application for reissue of said Letters Patent, of which the following is a specification.

Th'is'invention relates to a process of rolling flanged shapes or sections, snch iior in stance, as metal I-heams and bars. having a web between flanges.

In another application filed in the United States Patent Office September 29th. 1902, and bearing Serial Number 125,316, (here is claimed the process of rolling flanged shapes or sections comprising the provision of a special blank in which the mean thickness of each flange-portion and the thickness of the web-portion are in the proportion in which the said thicknesses exist in the finished product to which the blank is to he reduced, and duringthe reduction of the blank reducing the said thicknesses in the said proportion.

In the present application there is disclosed and claimed a process of rolling flanged shapes orsections consisting in a proportionate reduction of the web-portion and flange-portions of the blank'in area of cross-section by rolling pressures on the sides of the said blank-portions and on the edges of the flange-portions. and in provid ing a special blank in which the area of cross-section of the web-portion and the area of cross-section of each flange-portion are in the proportion in which the cross-scctionul areas of the said portions are to exist inthe finished product to which the said hlank is to be reduced, and substantially maintaining the said proportion in the cross secl ional areas of the said portions of the Blank during the reduction of the hlank.

n the accompanying drawings, Figures 1,

and use in] 2, 3 and 4 are cross-sectional ,views of a blank, shape or section illustratlng the re- (luction of the hlank by rolling pressures on v the web-portion and flanged portions of the blank during: succesive hlanlereducing passes of the blank. Fig. 5 "is an elevation diagrammatically and in central section, illustrating a universal mill employed in applying' rolling pressures to the sides of the web-portion and flange-portions of the hlank, and also showing supplemental rolls arranged a suitable distance from the universal mill and employed in applying rollire pressures on the edgcsioi the flangedportions. Fig. 6 is a vertical section on line 6-43. Fig. 5. lookin; in the direction indicated by the arrow.

The drawings also diagrammatically illustrate the two horizontalrolls c and d and the two vertical rolls f and f of a universal mill. The vertical rolls 7' have their axes in a vertical plane passing through the axes of horizontal rolls 0 and d. The horizontal rolls 0 and .d are arranged to operate upon opposite sides respectively of the Web-per timid and upon theinner sides of the-flangportions 6 and are relatively readjusted tween successive passes of the blank through the mill. The vertical rolls are arranged to operate uponthe outer sides of the flanges and are relatively readjusted between succesive passes of the blank through the mill.

The manner of supporting the rolls of a universal mill. means for adjustin the horizontal rolls'of the said mill towar and from each other, and means for adjusting the vertical rolls of the mill from and toward each other are too well known in the art to require illustration and description in this application.

A pair of horizontal rolls g, arranged to apply rolling pressures upon the edges of the flanges. are illustrated in Figs. 5 and 6, and. as shown in Fig. 5, are located at one side of and a suitable distance from and paralloliv with the horizontal rolls of the univi-irsul mill. in Fig. 5 a blank is shown in position not only heing reduced by a uni versal inill but heing also operated upon by rolling pressures upon the edges of the flanges hy the rolls owhieh are relatively adjusted as required preparatory to their operation. I

. The means of supporting rolls 9 and means for adjusting the said rolls to in *crease or decrease the space between them 5 tion in cross-sectional area 13 given to both the web-portion and the in the case illustrated being made. By the web-portion flanseport'ions, and an Lheam is shown proportionate reduction of and flange portions in area of cross-section isneant the same percentage of reduction in area of cross-section; that is, if the Web is'reduced a given per cent in area in one pass, the flanges same or substantially the same per cent of their area inthis same pass.

There is employed. prel'er:-1hly. a special blank having'the cros-ssectional area of its web-portion and the cross-sectional area of each flange-portion in the proportion which the cross-sectional area of the said flange- Ill) portion and the crossscctional area of the web-portion hear to each other in the tinished product to which the blank is to he reduced and rolling the said. flange-portion and web-portion andtherchy reducing the said portions in area of cros..-section in the proportion in which the cross-sectional area of 1hc said portions hear to each other in the blank and. in the finished product. In other Words. there is employed a blank having an area of cross-section in its Wcb-portion and an area of r -ross-section in each flangeporti n in the proportion which the cross-sew" fional. areas of the said portions exist in the finished product, and the said portions of the blank area of cross-section during each and every passage of the blank. The successive passes are formed by suitably adjusting the horizontal rolls 0 and 1] toward each other, and by suitably adjusting the vertical rolls f in wardly toward each other and also adjustin; the rolls y 9 toward each other all in such degree to insure the requisile proportional cross r-eclional reduction. i

To carry out thehcreinhel'ore mentioned norress; take an ingot and redu e it upon a logging mill to suitable dimensions so as to Form the hereinhei'ore described special blank. The blank. Whioln oi course, in suitably healed condition -is reduced. as hcreinlmforc stated. by the horizontal rolls 6 and (I and the vertical rolls f of the. universal mill and by edge-rolling rolls the supplemental flange g. Any suitable number plieation are reduced the are proportionately reduced in.

flange portions .simultaneously.- each of which operations snccesszyely reduces the cross sectional area of the shape in its Web and flanges in suhstantially the-same [)TOpGl" lion from the blank to the finished product and rolling the flange edges between said rolling operations. I

2. The process of rolling flanged shapes which consists in subjecting a blank having a web and flanges, the web of which is substantially of the same Width as that of the finished he to successive rolling operations. each of which consists in. rolling the faces of the web and of the fianges simultaneously and in thereafter rolling the edges of the flanges. ea h of said rolling operations simultaneously reducing the thickness of the Web and the mean thicknessand Width of each flange and at the same time reducing the cross sectional. area to the same proportionate extent 3. The process (if-rollingfianged shapes whicl'i consists in suhjecting a blank having: a web and flanges. the areas of the web and arr-as of the flanges having approximately the same relative proportions as they have in the finished product. firm-successive rolling operations on the sides of the web and of the flanges, and simultaneously therewith subjecting ea h of the'fianges to rolling pressures applied to the edges thereof by separate rolls. each of said rolling operations redu ing the thickness of the Web and also re during the mean thickness and Width oi each flange While simultaneously reducing the cross se tional area of the Web and of the flanges to the sa'me proportionate extent.

4. The process of rolling flanged shapes which consists in taking a blank, the thickness of the web of which andthe mean thickness of each flange of which substantially have the same relative proportions as they are to have in the finished product, and the areas of the web and the areas oi the flanges having approximately the same relative proportions as they have in the finished product. and subjecting the blank to a series-of rolling operations on the sides of the web and of the flanges simultaneously and then on the edges of the flanges, each of said of the shape to the same predetermined exand the web being preseiwed daring I ten5t.
